Locked Out

Being the office supervisor, I had to have a word with a new employee who never arrived at work on time. I explained that her tardiness was unacceptable and that other employees had noticed that she was walking in late every day. After listening to my complaints, she agreed that this was a problem and even offered a solution.
"Is there another door I could use?"

Robert Innes

Died 13 Mar 1933 at age 71 (born 10 Nov 1861).Robert Thorburn Ayton Innes was a Scottish astronomer who discovered Proxima Centauri (1915), the closest star to earth after the Sun. Invited by David Gill to the Cape Observatory, South Africa (1894), he became a successful binary star observer with the 7-inch refractor (1628 discoveries). His most famous discovery, Proxima Centauri is a faint star near the binary star Alpha Centauri, which is so far south it is not visible from most of the northern hemisphere. He was also the first to see the Daylight Comet of 1910, though this comet was found independently by so many people in the Southern Hemisphere that no single "original'' discoverer could be named. Innes recorded it on 17 Jan 1910.
